Day-14 | Configuration Management With Ansible |Puppet vs Ansible |Live Projects |

[@Cloudnp9458]

At first system administrator used to do upgrades, secure patches and installation on 100s of servers using shell script that had to loop over all 100s of servers. With cloud( micro service architecture) no. of servers increased and the compute/resources had decreased. Earlier we had to take care of distribution of OS(alpine, ubuntu), so the script might not work. To solve this configuration management came into picture. Puppet, chef and Ansible . Why Ansible over others? Ansible is much a push mechanism model. Write Ansible script at one instance and update all the worker nodes. Ansible is agentless, just put DNS or ip adress of servers in inventory file and have ssh password-less authentication configured, along with python3 installed by default in Linux distros. 2. Ansible also has feature of dynamic inventory. If you are creating 100s of servers in AWS cloud, Ansible will automatically detect new server. 3. Support both Windows, AIX and Linux all distros 4. Ansible is pretty simple, uses simple yaml manifest.

Notes of this video- Scenario- System admin has to configure 100s of servers, each with different OS like Ubuntu, CentOS, Windows. Tasks include updating OS, security patches, default installations like git, databases on servers. Issue- Doing this manually on every server is difficult. Hence, scripts were used. Powershell scripts for windows machines, other shells for Linux machines. Even in Linux machines, scripts varied based Linux flavours and type of script (bash, zsh, tsh, etc). This script will then loop over all servers to perform configuration tasks. With cloud and micro service architecture adoption, number of servers have increased further. Hence, even scripting approach is not very efficient. This led to concept of configuration management. Various tools are used for configuration management. Puppet and Chef were pioneering tools while Ansible, developed by Red Had is most popular. Why Ansible over Puppet? 1. Puppet = Pull mechanism, Ansible= Push mechanism. Eg. Managing 10 EC2- Write ansible playbook and push to all 10 EC2 2. Puppet uses Master-Agent architecture- Have to create Master server and configure all 10 EC2 as agents. Ansible is agentless. Write only ip/dns of machine in inventory file and have passwordless authentication enabled. In case of dynamic demand, auto-scaling is possible by changing inventory file. Even better- 'Dynamic Inventory' feature auto detects demand- doing away need to change inventory file. 3. Support for Windows is better in Ansible than Puppet 4. Ansible Playbook is written in YAML which is widely used. Puppet configuration is written in Puppet language. Issues with Ansible 1. Support for Windows is still not seamless 2. Debugging is not easy. Can run ansible in debug mode but debugging logs are not easy to understand. 3. Performance issues- when managing thousands of servers Enjoy!

For this for 1st question you have answered python but for 5th question you have asnswered yaml, can you pls confirm on this.

hello Abhishek, can you briefly explain the difference between Ansible playbooks and roles? How would you organize your Ansible project to ensure modularity and reusability of code?

[@chinmayesai4895]

Sir, please let me know if Iam right...? Ansible uses python for it's modules and YAML for writing playbooks?

[@ravindraravi7435]

Thank you ^^

[@Cloudnp9458]

Does Ansible support all cloud providers like AWS,azure,gcp.. Ans. For Ansible it doesn't matter what your cloud provider is. You only need public ip adress, is ssh access allowed publically to your machine(laptop).

[@ashishpandeypro]

Great introduction to Ansible Abhishek sir At the beginning of every video just say that it is the simplest, most interesting topic all (just like you did it in this video) It took so much load off my back and the presumption I formed was that the topic was easy and interesting.

[@Cloudnp9458]

You can write your own ansible module for installing load balancer for your own organisation in python. You can share them using Ansible galaxy so other team can utilize. Ansible galaxy acts as bridge. Sharing is always possible, give back to community and take benefits from community.

In AWS while creating EC2 instances - we can give some configurations right? So using ECS which has cluster of EC2 instances or something, can't we do the configurations?? Should Ansible be used? Also in Puppet when you are giving multiple slaves - so if 1000 machines are added. you go and add all the 1000 again in the master file?
